Seibu announced on March 10 that it will open a pop-up event "SEIBU STADIUM produced by Saitama Seibu Lions" for the first time in the event space on the 2nd floor of Building A of the Seibu Shibuya store for 9 days from March 15 ~ 23, where you can experience watching a baseball game without going to the ballpark.

This event was planned with the aim of targeting young people who have never been to a baseball game, and to encourage them to visit the stadium by experiencing the fun that can only be experienced at the stadium. There will be a zone introducing young Seibu players, a zone where you can actually touch and take photos with merchandise, a zone that recreates part of the locker room that players usually use, and a zone that recreates the stadium's benches and grass, allowing you to enjoy taking photos that can only be done at the actual venue.
